Product Overview
The Signal 241 Series Power Transformers are chassis-mount transformers designed for applications requiring superior isolation and low capacitive coupling. Featuring a split bobbin construction, these transformers offer reliable performance with a dielectric strength of 2500 Vrms Hipot. They are suitable for a wide range of power requirements from 2.4 VA to 100 VA and are available with single or dual primaries (115 V or 115/230 V) and single center-tapped secondaries. Terminals are of the solder lug/quick connect type, and insulation is Class B (130 C). These transformers are UL recognized and CSA certified, ensuring compliance with industry standards. Custom versions are available upon request.
